Embodiments disclosed herein provide an organic matter processing apparatus and method for the use thereof to convert organic matter into a ground and desiccated product. The organic matter processing apparatus includes a lid assembly that is positioned at the top or head of the processing apparatus and an air treatment system. The lid assembly is operative to open to allow a user to deposit organic matter into the processing apparatus or to remove a removable bucket contained therein. The lid assembly is operative to close and provide an odor containing seal that prevents or substantially mitigates escape of odor. The air treatment system uniformly distributes untreated air through an air treatment chamber to convert the untreated air to treated air, which is exhausted out of the processing apparatus.

A process gas treatment device for a process gas for treating a process material in a process apparatus and a method for treating process gas for the treatment of a process material in a process apparatus during a drying phase and a cooling phase.

The fog removal apparatus comprises a plurality of fog barriers for removing moisture in the fog by absorbing moisture in the fog and by allowing air to pass therethrough when the fog passes through the fog barrier on the wind, and a fog barrier support for supporting the fog barrier. The fog barrier comprises a perforated plate arranged on an outer surface of the frame to support the fog barrier; a coated mesh having a porous waterproofing function; a super absorbent sheet for absorbing a large amount of moisture from the fog passing through the fog barrier; a heating means arranged adjacent to the super absorbent sheet to heat and dry the coated mesh and the super absorbent sheet.

An air composition adjusting device includes: an oxygen separator that separates oxygen from external air to be supplied to a target space; a gas supply path including a high concentration gas supply path for oxygen through which the oxygen separator communicates with the target space; and a controller that performs an oxygen concentration raising operation of supplying a high oxygen concentration gas, which has a higher oxygen concentration than external air before being treated by the oxygen separator, to the target space through the high concentration gas supply path for oxygen.

An information management system provided with a plurality of external devices able to send and receive information and a server configured to be able to communicate with the external devices. The external devices are configured to send to the server the amounts of CO.sub.2 recovery recovered by the vehicles provided with the CO.sub.2 recovery devices. The server is configured to add up and manage the amounts of CO.sub.2 recovery sent from the external device.

An ultraviolet air sterilizer for disinfecting bacterium and virus includes a shell, a sandwich activated carbon cloth filter element, a nanometer titanium dioxide screen filter, an ultraviolet light source, a heat sinking kit, and a fan. The shell includes a shell body and a cover plate. The shell body is provided with an air inlet and an opening. The cover plate is provided with an air outlet. The sandwich activated carbon cloth filter element, the nanometer titanium dioxide screen filter, the heat sinking kit and the fan are arranged sequentially along an air path from the air inlet to the air outlet. The ultraviolet light source is configured for emitting ultraviolet light to the nanometer titanium dioxide screen filter. The air sterilizer has a compact small-sized structure and effectively removes ambient gaseous as well as particulate pollutants and kills micro-organisms harmful to health and well being.

A dryer includes a dehumidification filter containing a temperature responsive material with an upper critical solution temperature, a fan sending gas through the dehumidification filter, a heater heating the dehumidification filter, and a controller controlling the fan and the heater and switching an operation mode of the fan and the heater between a drying mode and a regeneration mode, wherein, in the drying mode, an object to be dried is dried with the fan sending the gas through the dehumidification filter that is heated by the heater to temperature higher than or equal to the upper critical solution temperature, and in the regeneration mode, the dehumidification filter is regenerated with the fan sending the gas through the dehumidification filter at temperature lower than the upper critical solution temperature.

A composition of matter having a porous cross-linked polymer network, quaternary ammonium ions in the cross-linked polymer network, and at least one counter ion in the cross-linked polymer network that is at least one of hydroxide or a counter ion capable of forming hydroxide upon reaction with water. A method to produce a porous material includes polymerizing a compound containing quaternary ammonium and a cross-linker using controlled polymerization and ion exchange in the presence of at least one of hydroxide or a counter ion capable of forming hydroxide upon reaction with water. A method to capture CO.sub.2, includes employing a sorbent comprising a quaternary ammonium ions in a porous cross-linked polymer network in an environment to adsorb CO.sub.2.

Provided herein are water harvesting systems, as well as methods of making and using such systems, for capturing water from surrounding air using a design that reduces overall energy costs of the systems and improve water harvesting cycle efficiency. The systems and methods use sorbent materials, such as metal-organic frameworks, to adsorb water from the air. The systems and methods desorb this water in the form of water vapor, and the water vapor is condensed into liquid water and collected. The liquid water is suitable for use as drinking water.

A fluid filter, filtering medium composition, and associated process for removing contaminants from feed and exhaust fluids used in fuel cell electricity generation, laboratories, the semiconductor and other industries to improve performance and extend useful equipment lifetimes and to clean fluids of sulfur compound contaminants, as well as to remove noxious NOx and halogen contaminants from feed and exhaust gases.
